I did a search and haven't been able to find an answer to this. Has anyone tried redeeming points by booking hotel through the Crystal Card Concierge and could validate if these bookings would be premier qualifying (at Marriott / SPG) so I get stay credits and can enjoy benefits as an elite member? Asking because using some portals (e.g. Citi's Thank You site) are likely going to show up as booked via OTA, but not sure about the Concierge here.
